Cold air intake for 1997 Chevrolet s10

Ok So I've been researching some way to add some power to my 4.3 Liter V6 Vortec. And I Found that putting a cold air intake add around 6 horsepower and the intakes run around 60-100 bucks. I really want too do this but will this run my engine? It allows more air into it so I was wondering if it will throw anything off, like air to fuel ratio, or starve it of gas. Any Information would be awesome.

I generally advise against these set ups. The air
intake system on your truck is already a cold air
intake system in that there is not a
thermostatically controlled air cleaner like was
used years ago. The throttle body is warmed by
a small coolant passage that goes around the
throttle body to prevent throttle body icing in
cool/damp weather. Also, the oil used for the air
filter on these will often contaminate the mass
airflow sensor, if equipped, and the intake air
temperature sensor. It will not upset the air/fuel
mixture because the computer is constantly
monitoring and adjusting that from information
it receives from the upstream oxygen sensor. It
maintains a 14 to 1 ratio under all conditions
once the engine is warmed up and in closed
loop operation. HTH. -Jim

And also, Oh the MAF sensor, I took the screen off to help increase air flow, and it made a big difference in power and added acceleration. Would that do any long term damge removing that screen? I still have it so I can put it back on

I hate to burst your bubble but there isn't a good way to add
power to a 4.3 without doing some heavy engine mods. All the
tricks you read on the Internet like the maf screen and removing
the baffle on the throttle blade will just affect throttle response.
Gm couldn't increase the power of the 4.3 until the end of its run
in the late 2000's. The 4.3 is a good motor nut the best way to
make more power is to do a motor swap.
